What it actually is

Logto is an open-source authentication and authorisation platform that implements OIDC, OAuth 2.1, and SAML on top of a Koa-based backend (packages/core). It provides pre-built sign-in flows, an admin console (packages/console), a customer-facing experience app (packages/experience), and an account portal (packages/account), targeting teams building SaaS and AI/agent applications who need multi-tenancy, enterprise SSO, and RBAC without hand-rolling protocol plumbing. It can be self-hosted via Docker Compose or Node.js, or consumed as Logto Cloud.

Why it's growing

The README's explicit positioning around Model Context Protocol and "agent-based AI architectures" is the most likely driver of the 1,488-star week, aligning the project with current interest in agent authentication. The breadth claims — SDKs for 30+ frameworks, out-of-the-box multi-tenancy/SSO/RBAC — reinforce it as a batteries-included alternative to hosted-only auth vendors. That said, no releases or commit titles were fetched for this analysis, so I cannot tie the spike to a specific shipped feature; the growth explanation rests on README positioning rather than dated change evidence.
